6.3 Replacement of the belt in the pre-milling unit
Before performing cleaning, maintenance or adjustment ope-
rations and/or replacing any part, it is mandatory to set the
main switch to 0 (zero) and lock it with a padlock. Remove
pressure from the installation by disconnecting the safety
valve, and then lock it with a padlock. Verify that all machine
parts are cool.
RECOMMENDATIONS:
- Verify the belt tension after the first 10 hours of machine
operation.
- Once a month, inspect the condition of the belt.
- Do not overtighten the belt as this will overload the bea-
rings.
Excessive belt tension also causes it to stretch and deteriorate
A
quickly.
To replace the belt proceed as follows:
- Remove the protection cover A (Fig. 6.6), removing the
screws.
To remove the belt, you must remove it from the motor pu-
lley B (Fig. 6.7) and remove it from the machine through the
space between the pulley B and the motor support C (Fig. 6.7).
To replace the belt follow the diagram (Fig. 6.8)
To find out if the belt tension is correct, check that the mea-
surement between screw F (Fig. 6.9) and support D (Fig. 6.9) is
44 mm. If necessary, act on screw F (Fig. 6.9).
